Abstract
The present application discloses a display panel comprising an array of pixel units, each pixel unit comprising a red sub-pixel, a green sub-pixel, and a blue sub-pixel; the red sub-pixel comprising a red light emitting portion; the green sub-pixel comprising a green light emitting portion; and the blue sub-pixel comprising a blue light emitting portion; at least one of the red sub-pixel, the green sub-pixel, and the blue sub-pixel comprising a white light emitting portion for enhancing brightness of the at least one sub-pixel. A first white color coordinate and a second white color coordinate are substantially the same. The first white color coordinate is a white color coordinate of combined light of light emitted from the red sub-pixel, the green sub-pixel, and the blue sub-pixel. The second white color coordinate is a white color coordinate of combined light of light emitted from equal area units of the red light emitting portion, the green light emitting portion, and the blue light emitting portion.
